What should you do if an adult, child, or infant becomes unresponsive after receiving thrusts?

When an adult, child, or infant becomes unresponsive after receiving thrusts, starting CPR is the appropriate action to take because it is crucial to restore circulation and breathing in a person who is not responding. This indicates that the individual may have suffered from an airway obstruction that was not resolved, leading to potential cardiac arrest.

Beginning CPR can significantly increase the chances of survival by providing artificial circulation through compressions and potentially delivering rescue breaths if trained to do so. This is a life-saving measure that helps maintain blood flow to vital organs, especially the brain, until emergency medical services arrive or the person regains consciousness.

In this scenario, performing the Heimlich maneuver again would not be appropriate as it is intended to clear an obstruction but is not effective on an unresponsive person. Waiting for the individual to regain consciousness can result in a delay that is detrimental to their health. Calling for help is important, but immediate action to initiate CPR is essential in such an urgent situation.
